Creatine Phosphokinase (CPK), also called creatine kinase, is an enzyme found mainly in your muscles, including the heart, and in the brain. When these tissues are damaged, CPK leaks into the blood. The total CPK blood test measures the overall level of this enzyme. A raised level usually points to muscle damage somewhere in the body.

Before the Test

Tell your doctor about recent heavy exercise, injuries, injections, or muscle strain, as these can raise levels.

Mention all medicines you take, especially cholesterol-lowering medicines.

Fasting is usually not required.

During the Test

A trained Orange Health Labs professional will collect your sample during the visit.

Follow the instructions given to you at the time of collection.

The sample is labelled and sent to the laboratory for testing.

Let the collection team know if you feel unwell during the procedure.

It is recommended:

To look into muscle pain, weakness, or cramps.

To check for muscle damage, including from injury or certain medicines such as statins.

To help assess heart or muscle conditions.

To monitor known muscle diseases over time.

When you have muscle symptoms your doctor wants to investigate. It may be repeated to see whether levels are rising or falling.
